Divisibility Rule of 620
The divisibility rule is a way to find out whether a number is divisible by another number without using the division method. In real life, we can use the divisibility rule for quick math, dividing things evenly, and sorting things. In this topic, we will learn about the divisibility rule of 620.
What is the Divisibility Rule of 620?
The divisibility rule for 620 is a method by which we can determine if a number is divisible by 620 or not without using the division method. Check whether 1860 is divisible by 620 with the divisibility rule.
Step 1: Check if the number is divisible by both 10 and 62, since 620 = 10 × 62.
Step 2: To check divisibility by 10, the number must end in 0.
Step 3: For divisibility by 62, apply the divisibility rule of 2 and 31 (since 62 = 2 × 31):
- A number is divisible by 2 if it ends in an even number.
- For 31, sum up the digits in groups of two from right to left and alternate subtracting and adding these sums (or apply any other known rule for 31).
Step 4: If a number is divisible by both 10 and 62, it is divisible by 620.
Example: Check if 1860 is divisible by 620.
- The number ends in 0, so it is divisible by 10.
- 1860 is even, so it is divisible by 2.
- Check divisibility by 31: 18 - 60 = -42 (as 31 goes into 42, it is divisible by 31).
- Hence, 1860 is divisible by 620.
Tips and Tricks for Divisibility Rule of 620
Learn the divisibility rule to help master division. Let’s learn a few tips and tricks for the divisibility rule of 620.
1. Know the factors of 620:
Memorize the factors of 620 (10 and 62) to quickly check divisibility.
2. Check smaller components:
Break down the divisibility into smaller components (like checking for 10 and 62) to simplify the process.
3. Repeat the process for large numbers:
For larger numbers, check divisibility by 10 first, then proceed to 62.
4. Use the division method to verify:
Use the division method as a way to verify and crosscheck results, helping to learn and confirm.
Common Mistakes and How to Avoid Them in Divisibility Rule of 620
The divisibility rule of 620 helps us quickly check if the given number is divisible by 620, but common mistakes like calculation errors lead to incorrect conclusions. Here, we will understand some common mistakes and how to avoid them.
Mistake 1
Not checking all factors.
Ensure you check divisibility by both 10 and 62.
Mistake 2
Forgetting to check for 10 first.
Check divisibility by 10 as it is simpler and can quickly rule out numbers.
Mistake 3
Confusing rules for 31 and other numbers.
Practice regularly to remember the rules for divisibility by 31.
Mistake 4
Not repeating the check for large numbers.
Break down and repeat checks for larger numbers to ensure accuracy.
Mistake 5
Misapplying subtraction or addition in checks.
Carefully apply the rules for summing or subtracting when checking divisibility by components.
Divisibility Rule of 620 Examples
Problem 1
Is 3720 divisible by 620?
Yes, 3720 is divisible by 620.
Explanation
To verify if 3720 is divisible by 620, we use the divisibility rule for 620 by first checking divisibility by 10, since 620 ends in a zero. 3720 ends in zero, so it passes the divisibility by 10. Next, check divisibility by 62. Divide 372 by 62, which equals exactly 6. Therefore, 3720 is divisible by 620.
Problem 2
Check the divisibility rule of 620 for 7440.
Yes, 7440 is divisible by 620.
Explanation
We check if 7440 is divisible by 620 by firstly confirming divisibility by 10, which it is, since it ends in zero. Then, consider divisibility by 62. Divide 744 by 62, which results in exactly 12. Therefore, 7440 is divisible by 620.
Problem 3
Is 1860 divisible by 620?
Yes, 1860 is divisible by 620.
Explanation
Verify if 1860 is divisible by 620 by first checking divisibility by 10. Since 1860 ends in zero, it passes this check. Next, check divisibility by 62. Divide 186 by 62, which equals exactly 3. Hence, 1860 is divisible by 620.
Problem 4
Can 2010 be divisible by 620 following the divisibility rule?
No, 2010 is not divisible by 620.
Explanation
To determine if 2010 is divisible by 620, check for divisibility by 10, which it passes. Next, check divisibility by 62. Divide 201 by 62, which does not result in a whole number. Thus, 2010 is not divisible by 620.
Problem 5
Check the divisibility rule of 620 for 8680.
Yes, 8680 is divisible by 620.
Explanation
To check if 8680 is divisible by 620, confirm divisibility by 10, which it passes. Then, check divisibility by 62. Divide 868 by 62, yielding exactly 14. Therefore, 8680 is divisible by 620.
